Alteraciones electroencefalográficas y queja cognitiva en adultos mayores con neurocistecercosis de la ciudad de Arequipa, Perú 2022

Neurocysticercosis is a parasitic disease caused by the ingestion of Taenia solium eggs that affects the central nervous system and brain, endemic in Peru. As an objective, it was proposed to know electroencephalographic alterations and cognitive complaint in older adults with neurocystecercosis in the city of Arequipa, Peru 2022. The study was descriptive-cross-sectional, carried out in the second semester, 2022. The sample consisted of 21 older adults from a Arequipa Hospital, with ages between 65-85 years, positive Western Blot results, axial tomography and magnetic resonance imaging. As a data collection instrument, epidemiological records, electroencephalogram results and a survey composed of 30 items were used. The data was stored in Microsoft Excel and processed with the Epidat 3.0 statistic to find out frequencies, percentages (%), confidence intervals (95% CI) and Chi square with p:< 0.05. As a result, a positive electroencephalographic alteration was found in 19.05% (n=4), of which 14.29% were male whose most affected age was 76-80 years with 9.52%, the EEG focus according to the number of lesions in the CT scan was 4.29% with multiple lesions and 4.76% with lesions from two to three without significant statistical association (X2: 3.0754; p: 0.2149), regarding electroencephalographic alterations, 9.52% had an EEG pattern of voltage asymmetry with POI polypoint paroxysms, 9.52% presented alterations in language elements 80.95%, 4.76% in spatial orientation and 4.76% delayed recall. In conclusion, more research is needed to better understand the relationship between cerebral cysticercosis and electroencephalographic abnormalities.
